This is the self absorbed abusive girlfriend introduced 20 May 2008, you can't throw away a character like that after a month.
I can imagine a hectoring self absorbed wife for Dilbert and as a foil for Dogbert.
I absolutely loved the first comic about the spam filter, funniest in a long while, but the subsequent five comics just strike me as a tired rehash of the same idea. There's too much repetition.
